ABSTRACT |
PURPOSE: Pilates exercise has been shown to improve core stability, strength, flexibility, muscle coordination and posture, but its effects
on BMD and bone metabolism were unknown. The purpose of this study was to examine the effects of 8 weeks of Pilates exercise on BMD
and bone metabolism in female university students.
METHODS: Eighteen subjects, aged 21.65±2.45 yrs, were randomly assigned into two groups: Pilates exercise group (Pilates, n=9) and
non-exercise control group (Control, n=9). The subjects in the Pilates group participated in the mat Pilates exercise program for 60 minutes
a day, 3 days per week for 8 weeks. Total body and lumbar vertebral BMD were measured by dual energy X-ray apsorptionmetry (DEXA)
before and after experience period. The blood samples were also collected before and after exercise, then the following variables were
examined as bone metabolic markers in serum: osteocalcin (OC), c-terminal telopeptide of type 1 collagen (CTx), insulin-like growth factor
type 1 (IGF-1) and growth hormone (GH).
RESULTS: Although total body BMD in the Pilates group was not shown to be significantly different before and after period, legs BMD and
lumbar vertebral BMD (L2-L4) significantly improved approximately 0.9% and 1.6%, respectively in the Pilates group (p<.05). L1 BMD (p<.05),
L2 BMD (p<.05), L3 BMD (p<.05), L1-2 BMD (p<.01), L1-3 BMD (p<.001), L1-4 BMD (p<.01) and L2-3 BMD (p<.001) also significantly increased
after period in Pilates group. However, serum OC, CTx, IGF-1 and GH did not show significant differences between pre-and post-periods
in all groups
CONCLUSIONS: These results suggest that prolonged mat Pilates exercise site-specifically improves legs and lumbar vertebral BMD, but it
did not affect total body BMD. These site-specific improvement of BMD was independent of GH and IGF-1. |
